Comment-to-DM and comment replies

When someone comments on your Instagram post, your AI agent or a routine can answer the comment and, when Instagram allows it, send that person a private reply in their DMs. On LinkedIn your agent can read and reply to the comments on your posts.

What it does

Comment-to-DM turns a comment on your Instagram post into a private conversation, and lets your agent answer comments on Instagram and LinkedIn.

Example

Commenter on your Instagram post: Price?

Public reply from your account: Just sent you the details in your DMs!

Private reply in their DMs: Hi! The linen shirt is in stock from S to XL. Here is the link to order, or reply with your size and we will hold one for you.

Why comments matter

A comment such as "price?" or "link?" is often a customer ready to buy. Answering it in public helps everyone reading, but the details are usually better in a private message, where the customer can ask a follow-up question.

Spaces lets your agent do both. It can reply to the comment so others see you answered, and send the commenter a private reply in their DMs when Instagram allows it.

What “when the platform allows it” means

Instagram decides when a business may send a private reply to a comment. When it allows one, the reply arrives in the commenter’s DMs as the start of a conversation. When it does not, Spaces does not try to work around it, and your agent can still answer the comment in public.

What your agent can do with comments

On Instagram and LinkedIn, your agent can:

list your posts and the comments and replies on each one
reply to a comment, or react to it
delete one of its own comments
on Instagram, send the commenter a private reply
on LinkedIn, mention people by their profile link

Letting a routine handle it

If you get the same comment again and again, a routine can do the work. It watches for a keyword in a comment, replies to the comment and, on Instagram, messages the commenter once, using the words you saved. Spaces lets your agent know when a new comment arrives, so it can answer anything the routine does not cover.

How to use it with your AI agent

Connect your accounts. In your Spaces dashboard, connect the accounts you already use. WhatsApp links with a QR code, the same way you would link WhatsApp on a computer. Instagram, LinkedIn, Messenger, X and email connect by signing in through a secure link.
Add Spaces to your AI agent. Add Spaces to the AI agent you already use, such as Claude Code, Claude, Cursor, Codex, ChatGPT, Grok, OpenClaw and Hermes. Each one has a short setup page, and most sign in through the browser with no code to copy.
Choose agent or routine. Ask your agent to answer new comments as they come in, or to set up a routine for a keyword such as "price" or "link", with the exact reply and private message you want.
Check the replies. Ask your agent which comments it answered today. Where approvals are on, comment replies and private replies wait for you to approve them.

Things you can say to your agent:

“Reply to the new comments on my latest Instagram post.”
“When someone comments "price" on Instagram, reply publicly and send them our price list in a DM.”
“Which LinkedIn comments on my post this week have not had a reply?”
“Thank everyone who commented on my LinkedIn post today.”

Setup for each AI agent is on Connect your AI agent.

Which channels support it

Instagram: Comment replies and reactions, plus a private reply into DMs when Instagram allows it.
LinkedIn: Comment replies and reactions on your posts. Private replies are not part of LinkedIn comments.

Hiding a comment is not available.

Comments on Messenger Pages and replies on X are not available.

Comments on Facebook Pages, YouTube, TikTok, Threads, Pinterest and Reddit are coming soon, with you approving every reply.

Limits that apply

Instagram comments: 4 an hour, 20 a day.
LinkedIn comments: 30 a day.
A private reply is a message from your Instagram account, so it follows the Instagram message limits, such as 80 messages a day.
A routine messages each commenter once, and nothing goes to someone who has said stop.

Every channel’s limits are on sending limits, and how Spaces protects accounts is on account safety.

FAQ

What is comment-to-DM?

It is when a comment on your post leads to a private message to the person who commented. On Instagram, Spaces sends that private reply when the platform allows it.

Does it work on LinkedIn?

Your agent can read and reply to comments on your LinkedIn posts and react to them. Sending a private reply from a comment is an Instagram feature.

Can a routine answer comments for me?

Yes. A routine can reply to a keyword in a comment and, on Instagram, message the commenter once with the words you saved.

Can my agent hide or delete other people’s comments?

No. Hiding comments is not available, and your agent can only delete its own comments.

Can I check replies before they go out?

Where approvals are on for your workspace, comment replies and private replies wait for you to approve, edit or reject them.

Does it work on Facebook Page comments?

Not yet. Facebook Pages and other social networks are coming soon, and you will approve every reply there.
